Title: Self-adjusting unwind brake
IPC: F16D49/00
Filed: 1967-11-16
Abstract: In a brake system for controlling a paper web roll when unwinding, a brake shoe 20 (Fig. 1) is pivotally carried on one end of an arm 18 pivoted on a pin 13. A second arm 22 is also pivoted on pin 13 and is connected to an extension 19 of arm 18 by an adjustable link 28. A pneumatic expansion chamber acts on one end of arm 22 to apply the brake shoe 20 to a drum 14, while the shoe is releasable from the drum by the weight of arms 18, 22. The link 28 is disposed, in clearance holes 26, 27 in the arm 22 and its effective length is adjustable to take up shoe wear, by rotating a collar 24 threaded thereon and which abuts a surface 30 of the arm 22, when the arm is moved to apply the brakes. The collar is automatically turned, by a spring loaded pawl 32 (Fig. 2) engaging ratchet teeth on the collar, should the shoe wear sufficiently to allow collar 24 to move a distance equal to one tooth pitch, when the arm 22 moves to its brake released position. The amount of movement of the brake arm 22 is limited by stops 38, 39. There may be at least one brake assembly on each diametrically opposite side of the drum, as shown in Fig. 1, or a plurality of brake assemblies may be provided side by side parallel to the drum axis.

Title: Method of hydrocarbon production by secondary recovery using a modified inverted 9-spot well pattern
IPC: E21B43/30
Filed: 1968-08-16
Abstract: A 9 spot well pattern (which may be one of a number in a production field) has four additional production wells arranged on a line passing through the central well and one of the surrounding wells. Combustion is initiated at the central well and air is injected into it, the other wells in the line being produced. The wells A, B Y are also produced. When the combustion front reaches the position number 1 and breaks through at the additional wells adjacent the central wall they are converted to air injection wells. As the wells are overrun by the combustion front they are converted to injection wells. After the wells X have been converted, wells Y are overrun and converted, the process being completed when the wells A, B are overrun. In a modification the wells A, B, Y are not put into production until the additional wells and the wells X are converted. In a further modification in which the wells A, B, Y are not put into production until the additional wells and the wells X are converted, the wells A, B are first put into production and converted when overrun, the process being completed on breakthrough at the wells Y. In another modification the additional wells are arranged on a diagonal of the pattern.
